You should change “Velocity” to “Speed.” If you double the speed, the time of arrival of your plane will be sooner. For example: Instead of 6 hours flight, your plane will arrive in 3 hours, if your plane doubled the speed to fly.
Q. What will happen if the initial speed of a projectile is doubled?
Thus doubling the velocity will quadraple the maximum height if the angle of projectile remains same.

Q. How is range affected by initial velocity?
The horizontal displacement of the projectile is called the range of the projectile and depends on the initial velocity of the object. If an object is projected at the same initial speed, but two complementary angles of projection, the range of the projectile will be the same.
Q. Does doubling initial velocity double max height?
Thus doubling the velocity will double the maximum height if the angle of projectile remains same.
Q. How would the horizontal range change if the initial velocity is doubled?
So, if initial velocity is doubled then horizontal range will be quadruple.
Q. What is the angle of projection at which horizontal range and maximum height are equal?
75.96∘
Q. How is the angle for maximum range affected by air resistance?
The maximum range will occur when the sum of the firing angle and the impact angle are 90 degrees so the firing angle must be reduced from 45 to achieve maximum range.
Q. What is the effect of air resistance on the range?
During the motion of a projectile, however, air resistance continuously retards its motion. As a result, the deviation of the actual trajectory of the projectile from that calculated by neglecting air resistance increases as the launch speed, size of the ball, and the time of flight increases.
Q. What are the factors that affect air resistance?
Air resistance depends on velocity, area, and shape of the object going through the air. Altitude, temperature, and humidity change air density and, consequently, its resistance. The higher the speed and the bigger the area, the higher the resistance.
Q. Does speed affect air resistance?
The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating. The object is said to have reached a terminal velocity.
Q. Does air resistance affect free fall?
Free fall occurs for falling objects that are only under the influence of gravity. During free fall, other forces such as air resistance do not affect the object’s movement. Once acceleration is zero, the object has reached terminal velocity, which is different for each falling object.
